crypto: arm64/aes-blk - honour iv_out requirement in CBC and CTR modes

2017-01-23T14:41:33+00:00

Update the ARMv8 Crypto Extensions and the plain NEON AES implementations
in CBC and CTR modes to return the next IV back to the skcipher API client.
This is necessary for chaining to work correctly.

Note that for CTR, this is only done if the request is a round multiple of
the block size, since otherwise, chaining is impossible anyway.

crypto: arm64/crc32 - accelerated support based on x86 SSE implementation

2016-12-07T12:01:22+00:00

This is a combination of the the Intel algorithm implemented using SSE
and PCLMULQDQ instructions from arch/x86/crypto/crc32-pclmul_asm.S, and
the new CRC32 extensions introduced for both 32-bit and 64-bit ARM in
version 8 of the architecture. Two versions of the above combo are
provided, one for CRC32 and one for CRC32C.

The PMULL/NEON algorithm is faster, but operates on blocks of at least
64 bytes, and on multiples of 16 bytes only. For the remaining input,
or for all input on systems that lack the PMULL 64x64->128 instructions,
the CRC32 instructions will be used.

crypto: arm64/crct10dif - port x86 SSE implementation to arm64

2016-12-07T12:01:17+00:00

This is a transliteration of the Intel algorithm implemented
using SSE and PCLMULQDQ instructions that resides in the file
arch/x86/crypto/crct10dif-pcl-asm_64.S, but simplified to only
operate on buffers that are 16 byte aligned (but of any size)

crypto: arm64/aes-ce-ccm - Fix AEAD decryption length

2016-12-01T13:06:37+00:00

This patch fixes the ARM64 CE CCM implementation decryption by
using skcipher_walk_aead_decrypt instead of skcipher_walk_aead,
which ensures the correct length is used when doing the walk.

crypto: arm64/aes-ce-ctr - fix skcipher conversion

2016-11-30T12:01:44+00:00

Fix a missing statement that got lost in the skcipher conversion of
the CTR transform.

crypto: arm/aes-ce - fix broken monolithic build

2016-11-30T12:01:41+00:00

When building the arm64 kernel with both CONFIG_CRYPTO_AES_ARM64_CE_BLK=y
and CONFIG_CRYPTO_AES_ARM64_NEON_BLK=y configured, the build breaks with
the following error:

arch/arm64/crypto/aes-neon-blk.o:(.bss+0x0): multiple definition of `aes_simd_algs'
arch/arm64/crypto/aes-ce-blk.o:(.bss+0x0): first defined here

Fix this by making aes_simd_algs 'static'.

crypto: arm/aes - Select SIMD in Kconfig

2016-11-29T08:11:14+00:00

The skcipher conversion for ARM missed the select on CRYPTO_SIMD,
causing build failures if SIMD was not otherwise enabled.

2016-11-29T08:06:56+00:00

Add the files that are generated by the recently merged OpenSSL
SHA-256/512 implementation to .gitignore so Git disregards them
when showing untracked files.
